They turns around fast

LANCELOT: Now, Lyra!

LYRA: Freeze!

She uses her magic to freeze the stalker (Ken)

LANCELOT: And get over here!

He uses his magic to drag Ken into the scene.

KEN: Hnnng!

LYRA: Ken?! Unfreeze.

She uses her magic to unfreeze him

KEN: Gasps What kind of spell was that?!

LYRA: Light Paralysis, what are you doing here?

LANCELOT: You've followed us all the way? Do you know something we don't?

LYRA: Lan, put down that flame!

LANCELOT: Don't you get it, Lyra?! He's after the Oathstone! He's a traitor!

Ken and Lancelot start fighting again

LYRA: This is ridiculous! Both of you, stop fighting!

KEN: I know from the start that he was bad news!

LYRA: Lan is not the one hiding in the dark!

LANCELOT: Just how much do you trust him Lyra?

LYRA: Just stop! Ken's been with the rebellion since the beginning, he's the one who got me in.

LANCELOT: Huh?

KEN: Hah!

LYRA: But I'm still disappointed in you! Get out, Ken!

KEN: Are you-

LYRA: Wait for us outside, we have a key to find.

KEN: Seriously? I'm not doing another musical number. One is enough.

KEN: No, I'll stay right here, I won't let him do anything to you.

LANCELOT: You know, I really despise you.

LANCELOT: I have my eyes on you. Come on, Lyra.

They continue through the tunnel and find a small room with a box in it

LYRA: Look, Lan, there's a box on the alter with a slot.

LANCELOT: Looks like the Oathstone will fit perfectly.

He gives the stone to Lyra

LANCELOT: It will probably activate some kind of trap or will it. Should we tell Ken?

LYRA: No, he'll be fine, let's do it.

She puts the stone in the slot.

LANCELOT: Open it carefully...

She opens the box

LYRA: Huh... Nothing happened.

LANCELOT: What's inside.

LYRA: Just like you said: a key.

They look at the key

LANCELOT: Lyra... The water is moving.

LYRA: That's more like it, I'm taking the key! Aah!

The key drains Lyra's Magic and knocks her out.

LANCELOT: Lyra?!

He grabs Lyra and runs back to Ken

KEN: What did you do to her?!

LANCELOT: Calm down, I didn't do anything! How is she?

KEN: Not a step closer, I'm dragging her out of here!

LANCELOT: The water is rising and the roof is collapsing, you will never make it out.

KEN: Do you really think I would stay here with you?!

LANCELOT: Yes, I'll put up a shield! Get closer.
